Largest Solar Parking Structures Provide MW Electricity

Largest Solar Parking Structures Provide MW Electricity

(7/12/11) By John Addison

It takes a lot of electricity to run Dow Jones, one of the world’s largest publishers and information providers. Dow Jones is now generating 3.6 MW of its own electricity with Solaire Generation Solar Parking Canopies. Solar parking structures allow organizations to reduce their utility bills, get more control of their own electricity generation, convert asphalt heat islands into attractive demonstrations of sustainability, and protect employees, customers and their cars.

I met with Solaire Generation CEO Laurence Mackler here at the Intersolar conference and exhibition being visited by over 22,000. Mackler explained that he founded the business because it made economic sense for his customers. They run the numbers and approve projects. Solaire is completely focused on parking structures with a patented dual-incline roof, the main surface south sloping for greatest efficiency. All Solaire parking structures use PV panels, not thin-film, to capture enough sun in the constrained space of the structures.

Increasingly, customers are also including solar electric car charging. Johnson and Johnson included 5 Coulomb Technology charge points in their 1.1 MW Solar Parking Canopy which uses SunPower panels. General Electric has a new Solaire parking structure that includes a number of the new GE charging stations.

The Arizona VA Hospital is installing 2.9 MW of solar panels from Kyocera and REC Group covering several parking lots. To research this article, I meet with Dr. Angiolo Laviziano, the CEO of REC Solar who is managing all aspects of this solar project.

The installation will add to a 302 kW single-axis tracker mounted system that REC Solar. Following the angle of the sun through the day, single axis systems are often 30 percent more efficient than fixed panels. Dr. Laviziano states that REC has 4.1 MW of added solar parking under contract from other VA Hospitals.

Like many organizations, the VA Hospital considered locating the solar panels on its roofs. This approach would have been more expensive; a uniform surface was not available due to rooftop located air conditioning and other equipment. Solar parking had the added benefit of giving employees and patients shading parking, instead of exposure to the blistering Arizona summer sun. Highly visible, the solar parking provides a positive public image which is often lost when solar is installed on roofs of high buildings.

REC Solar CEO Angiolo Laviziano is now expanding business for his 600-employee firm. REC plans to partner with several makers of electric charging equipment. Customers are expressing a growing interest in including electric car charge points in their electric parking structures. The least expensive time to install charging stations is when the power electronics, panels, and other equipment in being installed for the solar power, parking lighting, and other electric demands.

An informal REC survey of early adopters of electric cars, such as the Nissan LEAF and Chevrolet Volt, showed that these drivers also use solar power. Another 50 percent are interested in solar power. Angiolo is a perfect example of an early adopter of both. Years ago, he converted his Subaru to be an electric car using added lead-acid batteries in the trunk. He charges his car with his REC Solar system, a highly efficient two-axis system. He is the only owner I’ve met of an all-wheel drive electric car and certainly the only one who charges with a two-axis solar system.

Thousands of Parking Spaces Now Solar Shaded Globally

California State University Bakersfield (CSUB), Dr. Horace Mitchell and Sun Edison LLC, a leading worldwide solar energy services provider and a subsidiary of MEMC Electronic Materials (NYSE:WFR), co-hosted a “Flip the Switch” ceremony to commemorate the activation of the 1.2 megawatt (MW) solar parking canopy located on the CSUB campus.

The oil industry is one of the world’s biggest users of electricity. Saudi Aramco, Saudi Arabia’s national oil company has covered 4,500 parking spaces with 10 MW of thin-film CIGS solar from Solar Frontier, a company in which they are a major investor. Nikolai Dobrott, a Managing Director with Apricum estimates that the nation of Saudi Arabia may need as much as 30GW of added electricity in this decade, currently using natural gas, oil, and diesel for virtually all power generation; solar is an attractive form of diversification.

Solar developer Belectric is managing the solar project at Saudi Aramco’s headquarters in Dhahran. Over 120,000 CIS (Copper Indium Selenide) photovoltaic modules cover 4,500 parking spaces at the North Park offices parking lot, sheltering vehicles from the desert sun.

Automakers Massively Deploying Solar Parking Structures with Electric Car Charge Points

Envision has made its business focus to offer pre-configured and custom solar parking structures. Many offerings are designed to be attractive, converting asphalt urban heat islands into beautiful urban forests. The structures were originally designed by Envision founder and architect Robert Nobel.

In 2010, General Motors selected Envision to install its CleanCharge™ solar powered electric-vehicle (EV) charging stations integrated into EnvisionTrak™ tracking Solar Trees® at prominent GM locations.

Renault is not only working with Better Place to put 100,000 Renault Fluence electric cars on the streets of Israel and Denmark, it is also implementing a world record 55 MW of solar parking structures at various manufacturing facilities.

Whether an organization is providing for patients, students, or employees, solar parking structures are creating clean energy, shaded electric car charging, and attractive urban forests.

Renault Leads in Electric Cars and Solar Power for its Manufacturing

Renault Leads in Electric Cars and Solar Power for its Manufacturing

Renault solar roofRenault has received orders for 100,000 of its Renault Fluence Z.E. electric car from Better Place for massive deployment in Israel, Denmark, and other countries. The Renault-Nissan Alliance is the clear leader in freeway speed electric car sales with Nissan delivering the LEAF, and both using common electric drive system and lithium battery components.

These electric cars are zero emission from battery to wheels, but each car does contribute to tons of CO2 emission over its lifetime from manufacturing through thousands of electric charges to recycling of batteries and parts. Due to the 80 percent efficiency of electric drives compared to 15 percent efficiency of gasoline engine drives, electric vehicles produce 70 to 90 percent less greenhouse gas emissions than gasoline cars. Charging with renewable energy makes the reduction greater than a typical grid energy mix of 50 percent coal generation.

Renault wants to extend its leadership in carbon emissions reduction by installing the world’s biggest solar parking structure.  With a stunning 55 MW of solar energy, Renault will cut CO2 emissions by 30,000 tons a year. Project developer Gestamp Solar, using Trina Solar modules, is installing the biggest solar panel project in the global automotive industry. The project has added benefits of shelter cars, keeping them cooler in warm weather, and being easier to install than high roofs.

When the 450,000 m2 of solar panels are operational, they will cover an area equivalent to 55 football fields.  The project is part of Renault 2016 – Drive The Change, Renault’s strategic plan to reduce its carbon footprint by 10% by 2013 and by a further 10% between 2013 and 2016.

Renault has implemented several actions to reduce consumption at its plants (e.g. the zero carbon plant in Tangiers). With the solar parking and roof projects, Renault is showing its concern to conserve resources by diversifying the energy mix used to generate electricity, and particularly by using renewable energy sources. Solar panels will also cover the roofs of the delivery and shipping centers at the Douai, Maubeuge, Flins, Batilly and Sandouville sites, and the staff parking lots at Maubeuge and Cléon.

The start date for installation is mid-June 2011 and completion is scheduled for February 2012.

The Renault Fluence Z.E. lithium batteries can be switched at Better Place charging stations in minutes to give drivers unlimited range where switch Better Place Switch Stationstation networks are installed. They batteries can also be charged at traditional charge points. At switch stations, stored batteries could be charged with renewable energy off-peak and battery power could be provided to the grid during peak hours, thereby reducing the need for dirty coal power and inefficient natural gas peaker plants.
